Generally, this is because multiple processes in your job aborted
(exited with a signal or before MPI_FINALIZE) and mpirun only prints the
first abort message. You can modify how many abort status messages you
want to receive with the -aborted X option to mpirun, where X is the
number of process abort messages you want to see. The message generally
includes some information on what happened to your process.
